Application May 17, 1934, Serial No. 726,143 1 Claim. (o1; 38-67) Thisinvention relates generally to laundry machines and more specifically tomachine iron- .ers or mangles of either the chest or cylinder type.wherein a plurality of clothed rolls rotate within a heated chest ordrum, the work being ironed as it is passed therebetween.

The work is usually fed into the machine while damp. The heat given offby the heating element passes through the work and the clothed rolls.The resultant exchange tends to cause the work to adhere to the heatingmedium and rolls but the rotation of the rolls forces the work forward.However, when the machine has been in operation for any considerableperiod of time the clothed rolls themselves become heated to a highdegree and while the rolls will advance the work from the heatingmedium, nevertheless the tendency is for the work to adhere to therolls. If this adhesion is not overcome it naturally follows that thework will be wound around the rolls thereby defeating the neat ironingfunction.

To overcome such hazard, means have been employed, such as a series ofstrings held between the rolls and the heating medium so as the work ispassed it is ironed and will be forced downward or from the rolls. Othermeans have been to provide a series of fingers arranged tangentially tothe rolls and which bear against them in a direction opposite torotation so that the work is picked from the rolls after it has beenironed.

An objection to such devices is that the life of the cord is short dueto the heat and strain applied and the constant friction between thefingers and the rolls rapidly wears out the cloth. With either it isimpossible to re-clothe a roll without removing the entire workstripping means.

The present invention is designed to overcome these and other objectionsand, therefore has for its object the provision of means that willprevent the adhesion of work to the rolls and effectively strip ittherefrom during the ironing process.

Another object is to provide such means that can be adapted to existingtypes of machines without altering their present design.

A further object is to provide such stripping means that will notinterfere with reclothing the rolls or repairing other parts of themachine.

Other objects will appear and be better understood as the specificationproceeds, reference being had to the accompanying drawings forming apart thereof and in which:

Figure 1 is a perspective view of the stripping device assembled as itwould be applied to an ironing mangle. I a

Figure 2 is a sectional view, taken on line 2.2 of Figure 1.

Fig. 3 isv a transverse chest type mangle depicting the stripping deviceapplied thereto.

Figure 4 is a plan view of Figure 1.

Figure 5 is a detail disclosing the, manner retaining the strips on theframe.

Thus, it will be seen that the invention resides in the provision of oneor more strips adapted to pass beneath the rolls adjacent the beatingmedium and held in arcuate position by means of a suitable frame.

Referring more specifically to the drawings it will be seen that thenumeral l designates a heating element or steam chest, over whichrevolve padded ironing rolls 2. The work to be ironed, being designatedby the numeral 3, performed by passing it between the chest and rolls.

In order to remove the work 3 from'the rolls 2, in the event the workclings to the rolls, there is provided a series of thin narrow flexiblestrips 4, interposed between the chest I and the rolls 2. The strips arepreferably of rust proof metal.

In the chest type of ironing machines shown in the drawings, the strips4 are mounted in a frame which comprises pairs of end brackets 5,secured as by bolts 6, to convenient end portions of the machine, sothat they will clear the end rolls.

In the form shown in the drawings the brackets comprise oblongs eachpair of opposed ends being adapted to receive a side bar'l and a tie rod8.

The side bars i receive sleeves'or collars which are positioned on theside bars in opposed pairs midway between rolls 2.

The sleeves 9 have integral right angle extensions it] which verticallyreceive slidable uprights H. These uprights may be provided at the upperends with elbows l2 to receive crossbars [3 or the uprights ii andcross-bars l3 may form integral U shaped members.

To assemble the complete stripping device to an ironing machine,tappings are made at suitable locations in the outer end frame work toreceive the bolts 6, or other securing means to hold brackets inposition. The brackets, it will be understood, may be of any convenientdesign so that when in position they will clear the ma-- chine. the sidebars I are inserted and suitably secured to the machine by means such asbolts and washers I 4 after first mounting the sleeves 9 thereon.

section of a convention Through suitable borings in the brackets Theborings in the brackets are conveniently located so that the side bars Iand sleeves 9 will likewise clear the machine. If the brackets are ofsuch design as to require them, the tie rods 8 may then be positioned.

The sleeves 9 are then anchored in location on the cross bars 9 bysuitable means such as set screws. P5. The position of opposed sleevesshould be midway between rolls 2 so that the inverted U shaped crossbars II when inserted in the extensions IU of the sleeves, will likewisebe midway between rolls 2.

The cross bars, it will be noted, are Jvertically adjustable in theextensions [0 of the s1ee'ves 9 and are held in place as by set screwsl4. These bars should be located a distance below thelaxes of the rolls2 for a reason later to be explained.

Up to this point it will be observed that in order to assemble the frameon the ironing machine it was not necessary to disturb any of the" Thusit will be seen that at all times there is free access to the machineand stripping device. A roll can be reclothed without removing thestripping device. Likewise, should a stripper break, it can be replacedwithout removal of any part of the machine or of any part of thestripping device. The life of the strippers is prolonged by reason ofsecurement below the axis of the ironing rolls as there is less pressureapplied when they are thus located when the machine is in operation.
